Spi Virus (Mac)

Also Known As: Spi adware
Type: Mac Virus
Damage level: Medium

What is Spi?

Spi is an adware-type app that injects various advertisements into legitimate websites such as Google. In summary, it serves unsuspecting users with advertisements when they search. When installed, Spi also displays a number of pop-up windows asking people to provide a Mac user-account username and password.

Adware-type applications usually feed users with various advertisements such as pop-ups, coupons, banners, surveys, and so on. In this case, Spi displays ads even on websites such as google.com. Being annoyed by these unwanted ads is not the only problem - typically, clicking them results in redirects to dubious or even scam websites.

These opened websites promote unwanted apps that might be malicious. Furthermore, some might cause unwanted downloads and installations. When clicked, some ads execute scripts that start the download or installation process of unwanted applications.

Clicking them can thus lead to computer infections or other problems relating to privacy, browsing safety, and so on. Note that Spi also adjusts proxy settings and adds a certificate in the keychain. Note, however, that Spi does this only if the user gives permission.

It displays two pop-up windows: one asks users to enter a username and password to allow Spi to make changes to Certificate Trust Settings; the other asks users to provide the same credentials to allow Spi to modify the system network configuration. If you have granted these permissions, undo them.

Additionally, we strongly recommend that you remove Spi and other unwanted apps immediately.

The internet is full of adware-type and other potentially unwanted apps (PUAs). Generally, they are presented as legitimate and useful apps, however, when installed, rather than providing any real value, they simply cause problems. Installed PUAs usually lead to unwanted redirects, annoying ads, and even computer infections.

How did potentially unwanted applications install on my computer?

Adware-type and other PUAs are installed through clicked intrusive ads or together with third party software. Developers often use a deceptive marketing method called "bundling" to trick people into downloading and installing potentially unwanted applications with other (typically free) software that they download intentionally.

PUAs are usually hidden in "Custom", "Advanced" and other settings/options of software set-ups. Unfortunately, many people download and install programs without checking settings included in the set-ups. Leaving them unchanged allows bundled apps to be installed.

How to avoid installation of potentially unwanted applications?

Download all software from official and trustworthy websites, and using direct download links. To avoid unintentional downloads, do not use third party downloaders/installers, torrent clients, eMule (or other Peer-to-Peer networks), unofficial websites, and so on. Inspect all software set-ups, including "Advanced", "Custom", and other options/settings.

Deselect any offers to install additional software and only then proceed to the next step or finish the download or installation. Furthermore, bear in mind that many intrusive ads cannot be trusted. Once clicked, they redirect users to dubious/untrustworthy websites (gambling, pornography, adult dating, and so on).

Typically, unwanted redirects and advertisements occur due to PUAs installed on the system. If you experience these problems, check your browser for unwanted extensions, add-ons, and plug-ins and remove them. Apply this to any unwanted apps installed on the operating system.

If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
